Mike DeRosa

President / Founder

 

My first career developed into an Audit Manager position for Pattillo, Brown & Hill in Waco, TX. I was in public accounting for approximately 8 years. My audit specialty was State and Local Governments and Nonprofit entities. I also had expertise in airlines, banking and corporate holding.

My next career was Director of Finance for a large nonprofit organization, Center for Occupational Research and Development (CORD) in Waco, Texas that had a for-profit publishing manufacturing and distribution company. It was here that I chose MAS 90 (Level 1.x DOS) as the solution for this organization and performed my first implementation. I was in this position for just under 5 years.

After stabilizing the information system at CORD, I was looking for a new challenge and accepted a position with the re-seller that sold the MAS 90 system to me, MicroAccounting Solutions in Dallas, TX. They needed someone to manage their Austin, TX office and a Sales Consultant for Central and South Texas.

I left MicroAccounting in 1999 to start my own consulting company about a year after MicroAccounting was sold to a new owner. We started with no leads or clients and closed our first sale 90 days after starting. DeRosa Mangold Consulting today is a leader in MAS 90 and MAS 200 solutions, placing 18th in the country in new MAS 90/200 customers in FY2007.

My goal is for our company to be the best MAS 90/200 service provider in the country, not necessarily the largest, but the most responsive that will bring all of our resources to bear, inside and outside of our company, to serve the client.

Liz Ortega emerged in 2000 at DeRosa Mangold Consulting after relocating back to Texas from California. She has previously worked with a variety of distribution and service companies from shipping and receiving to accounting. As a former user of MAS 90 and other professional accounting technology, Liz became an adequate fit for our company and naturally progressed to the technical side of the trade. On her off time, she enjoys keeping company with her family and fostering animals (mostly kittens) who are in critical need of care.

Liz prides herself on being someone who has a wide knowledge of the software packages she uses. Succeeding expectations with her ability to go above and beyond the norm to collaborate and guide those who require assistance.
